SYNOPSIS

9       #include <libknet.h>
10
11       int knet_link_get_status(
12           knet_handle_t              knet_h,
13           knet_node_id_t             host_id,
14           uint8_t                    link_id,
15           struct knet_link_status   *status,
16           size_t                     struct_size
17       );

DESCRIPTION

20       knet_link_get_status
21
22       knet_h - pointer to knet_handle_t
23
24       host_id - see knet_host_add(3)
25
26       link_id - see knet_link_set_config(3)
27
28       status - pointer to knet_link_status struct
29
30       struct_size  -  max  size  of  knet_link_status - allows library to add
31       fields without ABI change. Returned structure will be truncated to this
32       length and .size member indicates the full size.

RETURN VALUE

52       knet_link_get_status returns 0 on success -1 on error and errno is set.
